IMPROVEMENT IN MACHINES FOR MAKING HORSESHOE-NAILS- Specificationforming part of Letters Patent No. 161,379, dated March 30, 1875application filed October 28, 1874.

To all whom "it may concern:

Be it known that I, ALBERT D. BnvGHAM, of Nashua, of the county ofHillsborough and State of New Hampshire, have invented a new and usefulImprovement in Machinery for Making Horseshoe-Nails; and do herebydeclare the same to be fully described in the following specification,and represented in the accompanying drawings, of which-- Figure l is atop view, Fig. 2 a front elevation, Fig. 3 a side elevation, and Fig. 4a longitudinal and vertical section, of my invention, as arranged withthe driving-shaft frame, an-

' vil swage-roller, and lateral hammers of a horseshoe-nail machine, thepurpose of my improvement being to operate the swage-roller relativelyto the anvil, and with more power and to better advantage than when suchroller is carried by an arm extended from the shaft.

In carrying out my invention I employ an eccentric and its collar, aslide or arm, and a rock-shaft, and support the swage-roller byprojections from the said collar, all as represented in the saiddrawings, in which A denotes the frame of the machine, provided withstandards a a and b 1). Within this frame is the anvil B, whose uppersurface is usually inclined more or less from the horizontal plane, suchanvil and the lateral hammers G G being as usually made and providedwith mechanism for actuating said hammers. The driving-shaft D has itsbearings in the standards a a, and is arranged over the anvil. Suchshaft at its middle is provided with an eccentric, E, to whose collar Fthe swage-roller G is applied by means of and between arms 0 0 extendedtherefrom, and provided with bearings to receive the journals of thesaid roller. From the collar F there projects a slide arm or rod, H,that goes laterally and loosely through a rockershaft, 1, arrangedbetween and pivoted to the two standards b b. This rock-shaft andslide-rod permit the collar of the eccentric to move up and down andforward and back, or conform to the motions of the eccentric, and theymaintain the collar and swage-roller in their due relations to theanvil. The eccentric not only operates to depress'the swage-roller withmuch force but to move it longitudinally over the anvil to greatadvantage, in order to effect the swaging or tapering of a nail -blankwhen resting on the anvil.

What I claim in the horseshoe-nail machine as my invention is Theeccentric E, its collar F, the slide rod or arm H, and the rock-shaft I,arranged and applied together and to the driving-shaft D, swage-rollerG, and the back standards 12?), all essentially as and to operate asspecified.
